Some of you may have been following the Arden project (reported in Nature and the Chronicle of Higher Education). I’m pleased to announce that the project has come to fruition. With generous support from the MacArthur Foundation, we have created a fun game environment and used it to conduct a month-long experiment. Our experimental question (kept secret up to now) was: Are fantasy game players economically “normal”? Or on the contrary, when they make themselves into elves and dwarves and hobbits, do they stop taking economic decisions seriously? We created two virtual worlds, one an exact copy of the other, except that in the experimental world the price of a simple healing potion was twice as high as in the control. If people are taking prices seriously in this fantasy environment, they should buy fewer of the potions when potions are more expensive.

It is good to see that the results from the experiment will be released soon. Good luck to all of the presenters at ICA!
